Trevison had been the cool boxer, carefully trying out his opponent. He had felt little emotion save that of self-protection. At the beginning of the fight he would have apologized to Corrigan--with reservations. Now he was stirred with the lust of battle. Corrigan's malignance had struck a responsive passion in him, and the sodden impact of fist on flesh, the matching of strength against strength, the strain of iron muscles, the contact of their bodies, the sting and burn of blows, had aroused the latent savage in him. He was still cool, however, but it was the crafty coolness of the trained fighter, and as Corrigan crowded him he whipped in ripping blows that sent the big man's head back. Corrigan paid little heed to the blows; he shook them off, grunting. Blood was trickling thinly from his lips; he spat bestially over Trevison's shoulder in a clinch, and tried to sweep the latter from his feet. The agility of the cow-puncher saved him, and he went dancing out of harm's way, his spurs jingling. Corrigan was after him with a rush. A heavy blow caught Trevison on the right side of the neck just below the ear and sent him, tottering, against the wall of the building, from which he rebounded like a rubber ball, smothering Corrigan with an avalanche of deadening straight-arm punches that brought a glassy stare into Corrigan's eyes. The big man's head wabbled, and Trevison crowded in, intent on ending the fight quickly, but Corrigan covered instinctively, and when Trevison in his eagerness missed a blow, the big man clinched with him and hung on doggedly until his befoggled brain could clear. For a few minutes they rocked around the room, their heels thudding on the bare boards of the floor, creating sounds that filtered through the enclosing walls and smote the silence of the outside world with resonant rumblings. Mercilessly, Trevison hammered at the heavy head that sought a haven on his shoulder. Corrigan had been stunned and wanted no more long range work. He tried to lock his big arms around the other's waist in an attempt to wrestle, realizing that in that sort of a contest lay his only hope of victory, but Trevison, agile, alert to his danger, slipped elusively from the grasping hands and thudded uppercuts to the other's mouth and jaws that landed with sickening force. But none of the blows landed on a vital spot, and Corrigan hung grimly on. At last, lashing viciously, wriggling, squirming, swinging around in a wide circle to get out of Corrigan's clutches, Trevison broke the clinch and stood off, breathing heavily, summoning his reserve strength for a finishing blow. Corrigan had been fearfully punished during the last few minutes, but he was gradually recovering from his dizziness, and he grinned hideously at Trevison through his smashed lips. He surged forward, reminding Trevison of a wounded bear, but Trevison retreated warily as he measured the distance from which he would drive the blow that would end it
